ABSTRACT
Canine alerting to oncoming seizures, hypoglycemic episodes, and migraines has been a subject of articles in the popular press and scientific journals for decades in the case of epilepsy, almost as long in the case of diabetes, and more recently in the case of migraines. Advance alerting has sometimes been reported by sufferers of other conditions.1 Chemical phenomena have been linked with such conditions, and it has often been suggested that the dogs are using their olfactory skills to recognize changes in the way that the humans smell, though behavioral changes in the humans have also been postulated, and it is possible that dogs are assembling a number of different types of cues in reacting to these episodic conditions.
